Abstract:	We present a new application of the class cover problem to statistical pattern classification. The goal of the class cover problem is to find a set of covering balls to cover one class of points while avoiding another class of points. We present an adaptive method for choosing the radii of the covering balls. The purpose of the method is improved classifier performance.
